Aspen has no shortage of chichi resorts for your chichi pals but few others (excluding the St. Regis) come close to the perks of Little Nell. Offering 26 "ski in, ski out" residences at the base of the mountain, they've got a pet package to rival any in town. First up, you'll get a copy of their own Petiquette handbook with guidelines for pets and owners along with lists and reviews of recommended animal-friendly hiking trails. When you arrive, find a cozy bed for each of you and, if your trip was too long, order room service and rest up before exploring the town's offerings. Off their in-room dining menu, I recommend treating your pooch (or even a borrowed one) with a "Puppy’s Jet Lag Kit" including custom gourmet doggie biscuits and his own pet menu — tenderloin of beef with eggs and rice, grilled chicken breast with carrots and brown rice, or grilled salmon with scrambled eggs — served up on a custom place mat and bowl set. When you're ready to explore, add personalized brass ID tags, and walk him yourself (or use their services) then get him cleaned up with their recommended groomers. While it used to be free of charge, a $100 charge per room applies for guests visiting with their pets . . . but that includes up to two hours of pet sitting!
